Luka, 21, posed on the carpet wearing all black.
The young star sported a t-shirt that said, “Movie Star Junkie,” wore jeans, a bomber jacket, and leather accessories.
The Grown-ish star also took pictures on the carpet with the Montblanc North America President Sylvain Costof and Montblanc VP of Digital Sales Florent-Aymeric Dubiez.
The 21-year-old attended the party with his dad, Clark, and younger brother, Callum, although they opted to skip the carpet.
Luka showed off his modeling skills and posed in front of some items from the collection at the party. The limited-edition collaboration has different leather accessories made by Montblanc with BAPE’s signature camouflage print.
The model later joined DJ Va$htie on stage. She was head-to-toe clad in BAPE gear.
